Definitions

  • the present invention is related to a head assembly for a vein stripping instrument.
  • Vein strippers or vein extractors are used in surgery for extracting veins, primarily veins in the extremities affected by varices or phlebectasies.
  • British Patent No. 1 290 282 describes a varices bougie provided with a head or body at one end and having the opposite end shaped as a helix.
  • a vein stripper having a head releasably attached, in which head the cable or wire may be entered through a longitudinal slot is described in British Patent No. 1 371 176.
  • U S Patent No. 3 764 427 describes a vein stripper wherein a conical head can be releasably mounted on an enlarged end portion of a cable.
  • a vein stripper with a releasable head is advantageous in providing for introduction of the stripper cable into the vein in one direction, assembling a head at the front end of said cable and extracting the vein and stripper in the direction opposite to the direction of introduction.
  • Such previously known vein strippers have the drawback that the head cannot be securely attached to the cable and may thus be released by accident, e.g. when the surgeon relaxes the instrument during the extraction operation or when pushing the stripper backwards.
  • the object of the present invention is to provide for a vein stripper having a head attachable at one or both ends of a stripper cable and being releasable therefrom, such head being safely fixed when attached to the cable. Further objects are to provide for a vein stripper in which the head can be easily and quickly attached to the end of the stripper and wherein the end of the cable at which the head is to be attached is smooth and can be designed in such manner that the introduction thereof through the veins is facilitated.
  • a head assembly for a vein stripping instrument comprising a head having a longitudinal slot extending into a central bore, wherein a cable of a vein stripper can be received, said bore having an enlarged portion opening at a distal end of the head, said head having one or more hook means projecting from the distal end thereof and being lockable over an edge of a cap member, said cap member and head forming a head assembly lockable over an enlarged end portion of the vein stripper cable.
  • the cap member is preferably of cylindrical shape and has a lateral opening for each hook means of the head.
  • the hook means of the head are lockable over an inner edge of the cap member by snapping out in a radial direction.
  • the hook means projecting from the distal end of the head consist of the two hooks placed opposite to each other.
  • a head of a vein stripper is denoted 1.
  • Said head has a proximal end surface 2 which will engage the vein to be extracted.
  • a longitudinal slot 3 extends into a central bore 4 having an enlarged distal portion 5.
  • From the distal end of the head two integrally formed hook members 6 project having lateral edges 7.
  • a cap 8 has the shape of an open cylinder having edges 9 and a bridging tapered end portion 10.
  • a vein stripper cable 12 has a cylindrical enlarged end portion 13 with a rounded distal end 14 and a conical proximal segment 15.
  • the cable 12 is introduced through the slot 3 into the cental bore 4 of the head and the enlarged end portion 13 is pulled into the enlarged distal portion 5 of the bore.
  • the cap 8 is pressed over the hooks 6, which are of sufficient flexibility to yield inwards and snap back to a position where the edges 7 are in locking relationship with the edges 9 of the cap, thus forming a head assembly firmly locked over the end portion 13 of the cable.
  • the head 1 can be substituted with a head of larger diameter 16 or a head of smaller diameter 17 if required.
  • the same cap 8 may be used.
  • the vein stripper cable shown in Fig. 6 has a helical portion 18 spaced from the enlarged end portion 13 by a short straight segment.
  • the cable is made up of a tube of plastic material and reinforced with a steel wire 19.
  • the cable is provided with a conventional vein stripper head 20, thus enabling vein extraction in the direction of introduction in cases when the surgeon finds such manner of extraction preferable.
  • said opposite end may have another enlarged end portion 13 or the end may be shaped for attachment to a handle.
  • the head assembly may be prepared of a plastic material such as acetal polymer or polyamide by injection moulding.
  • the dimensions of the enlarged end portion 13 of the cable and the corresponding cavity in the head 1 are preferably chosen thus that the head will be firmly held after pressing the end portion into the cap 8.
